Specification of Letters Patent.

Patented Aug. 10, 1909.

Application filed March 1908. Serial No. 423,091.

To all whom it may concern:

Be it known that 1, JAMES G. B. LAMB, a citizen of the United States,residing at Williamston, in the county of Inghamand State of Michigan,have invented a new and useful Door-Hanger; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in door hangers, especiallydesigned for doors of cars particularly, of the freight type.

It has for its object among other things, to provide for readilysuspending the door in position and for its convenient manipulation, asin moving it into open and closed position and for its lateral oroutward movement when that may become necessary in order to move thedoor into open position, such a contingency arising as when lateralpressure from within of the car con tents may render it difficult tootherwise move the door; and to carry out these ends in a simple,expeditious and eifective manner.

Said invention consists of certain instrumentalities or featuressubstantially as hereinafter fully disclosed and pointed out by theclaim. I

In the accompanying drawings, illustrating the preferred embodiment ofmy invention, Figure 1 is a front elevation thereof in the usualparallel relation to the car body. Fig. 2 is a vertical section producedthrough Fig. 1, the section line passing through the door. Fig. 3 is aview of like general character, with the door standing outward at anangle to the car body. Fig. 4: is an enlarged perspective view of ahanger with its respective parts or members disassembled. Fig. 5 is aperspective view of a portion of the track-way. Fig. 6 is a perspectiveview of the door 3, and its lo clr ing mechanism. Fig. 7 is a sectionalView on line 77 of Fig. 1. Y

In regard to the drawings, which as will be observed, thoroughlyillustrate the invention, 1 designates the track-way, which is in theform of a trough. This trough -is formed of three lenghs of sheet metal2 which are provided'with side flanges 3 and P. The flanges 3 are bentto form shoulders 5", against which the longitudinal edges of theflanges P abut, as shown clearly in Figs. 2, 3 and 5. The lower lengthsof metal are provided with flanges 6", which, as is said door beingevident, form the rails or tracks, upon which the wheels 12 travel, asthe door 3 is moved horizontally. As clearly disclosed in Fig. 5 of thedrawings, it will be observed that the flanges P overlap the flanges 8-,and in constructing the track-way or trough inthis manner, wood blocks 7are positioned within either end thereof, and

into which blocks the screws 8 are forced,

as shown clearly in Figs. 1 and 5. The blocks 7 provide means wherebythe lengths of metal are held in their proper position.

The usual door 3, which is hung in position parallel with the side orlateral portion of the car or structure, is provided at its upper edgewith hangers 4:, arranged near its forward and rear edges, respectively,and adapted to suspend the door from the track way 1, for endwisemovement, or allow of moved laterally or outwardly from the car-body aswill be explained, and when the said door is in a closed position, thesame may be held in such position. Each of said hangers consists of astrap hinge member 5 and an upper end truck member 6, the former beingsuitably extended down upon, and bolted to the outer side of the doorand having its upper end portion carried inwardly at a right angle as at7, over the top edge of the door and further extended upwardly toprovide for effecting connection with the truck member in alinement withsaid edge of the door and for centrally suspending the weight. of thelatter. Said hinge member has its extreme upper end formed or terminatedinto an elongated eye 8 which receives a bolt or pintle 9 pivotallyconnecting or hinging it to the truck member (3, the lastnamed beingformed with a stirrup 10 having alining eye-ended terminals also receiving said bolt or pintle for the purpose aforesaid. Said truck member hasalso an integral upwardly extending central plate-like portion 11equipped near its ends with pulleys or wheels 12 traveling upon therails of the traclrway 1, fixed as stated, to the car body for the readyendwise movement of the car-door, which latter also, by reason of thehinging or pivoting connection aforesaid, is adapted as above intimated,to be swung or moved outwardly from the car body, for a purpose noted.

The aforesaid combination and arrangement of parts provides a simple,convenient and effective door hanger and one which facilitates thesuspending of the door, in addition to being characterized by theadditional advantages above recited.

The door 3 is provided with a new and useful locking mechanism, by whichthe same may be prevented from being swung outward, at an angle, asshown in Fig. 3 of the drawings. This locking mechanism comprises a boltretaining strip 16, which is fastened by means of screws or othersuitable means 17 to the car body, as shown clearly in Figs. 1, 2 and 3of the drawings. The opposite edges 18 of'the door 3 are provided withmetallic plates 19, which are secured thereto by screws or othersuitable means 20; these metallic plates 19 are provided withdove-tailed guides 21, between which the sliding bolts or bars 22operate, as will be clearly seen in Figs. 6 and 7 of the drawings. Thesebolts or bars engage between the metallic strip 16 and the body of thedoor, so as to prevent outward movement of said door. To the upper ends28 of said rods or bars are pivoted links 24, the upper ends of whichlinks, are pivoted, as at 25, to the arm 26 of a U-shaped gravitatinglever 27, which arms 26 are provided with eyes 28, which engage eyes 29secured to the door 3, as clearly shown. The cooperating eyes 28 and 29form a pivotal connection for the said U-shaped lever, as will beclearly manifest. The upper ends of said bolts or bars are slightlyoutwardly bent so as to allow a pivotal connection with the said links,which are disposed between said bolts or bars and the metallic plates,as seen clearly in Fig. 6 of the drawings.

From the foregoing, the essential features, elements and the operationof the device, together with the simplicity thereof, will beclearlyapparent.

Having thus fully described the invention, what is claimed as new anduseful, by the protection of Letters Patent, is

The combination of a car-body and a track-way, of a pivoted, slidabledoor suspended from said track-way adapted to be manipulated foruncovering or closing an opening in said car-body, said door havingdovetailed guides secured to either side thereof, sliding bolts havingoffset portions mounted in said guides, a U-shaped gravitating leverpivoted to the outer face of said door, and links pivoted at their lowerends to the said offset portions while their upper ends are pivoted at apoint between the pivots and the swinging free portion of saidgravitating lever, the gravitation of said lever assisting in moving orsliding said bolts, as and for the purpose specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
